## NTSB investigations (1)

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.

- [NTSB NYC89LA173](https://openairdocs.org/ntsb/NYC89LA173), Jul 23, 1989: Schweizer 1-23 (N91867), Eighty Four, PA, substantial damage. Probable cause: POOR HANDLING OF THE GLIDER DURIG LANDING. THE PILOT OVER CORRECTED AND CAUSED THE NOSE TO STRIKE THE RUNWAY SURFACE. DIRECTIONAL CONTROL WAS LOST, RESULTING IN A GROUNDLOOP.

## FAA accident and incident reports (1)

From the FAA Accident/Incident Data System. Reports are matched to registry aircraft by N-number and event date, checked against the reported make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.

- [Accident 19890723025189A](https://openairdocs.org/incident/19890723025189A), Jul 23, 1989: Scwzer SGS123 (N91867), Eighty Four, PA, Substantial damage. Excessive speed on final, over controlled on landing. Bounced and ground looped. Impact wrinkled wings of glider.
